Title: Analyzing the Role of the Agriculture Section in Growing Iran's Economy Authors: Zaroki, Shahryar; Rezvani, Saeed Abstract: The agricultural sector is one of the most fundamental economic divisions. We investigated the effect of value-added indicators of the agricultural division on Iran's economic growth by an autoregressive method with distributive intervals (ARDL) during the period 1968- 2015 in this study, regarding the significance of the agricultural sector and the role of its value-added on Iran's economic growth and ultimately, on the growth of the national economy. According to the first model, it was concluded that the value-added of the agricultural division in the short and long term has a positive and negative effect on economic growth, respectively. Additionally, the agricultural division's investment index in both short-term and long-term periods is statistically significant and positively affects economic growth. The index of trade liberalization of the agricultural sector has no positive effect on the economic growth in the short term, but it has a negative and significant effect on economic growth in the long term. Subsequently, according to the second model, the value-added index of the agricultural sector in the short term has no significant effect on economic growth but has a negative and significant effect on economic growth in the long term. Also, the residual index of agricultural facilities index has no significant effect on economic growth in the short term but has a positive and significant effect on economic growth in the long term. The effect of the index (first-time interruption) degree of economic openness of the agricultural division in the short term has no significant effect on economic growth, but has a positive and significant effect on economic growth with two interruptions, but has a negative and significant effect on economic growth in the long term. Hence, the government must seriously consider the agricultural division to realize its macroeconomic objectives. Description: PP:1-12

Title: Zero Next to Zero (ZnZ) Method: A New Approach for Solving Transportation Problem Authors: Uddin, Md. Main; Khan, Aminur Rahman; Sultana, Nahid; Uddin, Md. Sharif Abstract: Transportation Problem (TP) plays the role in cost planning for distributing the commodities from the sources to the destinations. Initial Basic Feasible Solution (IBFS) is the first step to the way of obtaining an optimal solution. There are various algorithms to find IBFS. The best solution method gives optimal cost with the least iteration. In this paper, a new solution procedure namely Zero next to Zero (ZnZ) method has been proposed to determine the IBFS for TP. The aim is to obtain a total transportation cost that is similar or close to the optimal solution with the least iteration. The performance of the proposed algorithm is evaluated using two characteristics and compared with the existing algorithms available in the literature. The comparison results indicate that the proposed approach yields better results by taking comparatively very less effort and computation. Description: PP:13-23

Title: An Inventory Model for Deteriorating Item with Time Dependent Demand and Permissible Delay in Payment Under Inflation Authors: Hakim, Md. Abdul Abstract: In this paper, we have developed an inventory model for deteriorating items with timedependent demand considering the inflation effect on the system. Shortages if any are allowed and partially backlogged with a variable rate dependent on the duration of waiting time up to the arrival of the next lot. The corresponding problem has been formulated as a nonlinear constrained optimization problem, all the cost parameters are crisp valued and solved. A numerical example has been considered to illustrate the model and the significant features of the results are discussed. Finally, based on these examples, sensitivity analyses have been studied by taking one parameter at a time keeping the other parameters as same. Description: PP: 25-32

Title: Finding Equilibrium Price and Quantity Using Fuzzy Linear Demand and Supply Equations Authors: Islam, Sahidul; Alam, Md. Ashraful; Hossain, Sakib Abstract: In this research, we explore the supply and demand model and pursue the factors that influence demand and supply. We discuss the shifting of equilibrium points for the changes of supply and demand. Equilibrium is the point where both the consumers’ and producer’s willingness agree. Since there exists so many factors affecting the equilibrium point and the data are imprecise, we are aiming to find the equilibrium interval rather than the crisp point. We conduct our work with the help of interval arithmetic of fuzzy numbers and the classical method of solving the system of fuzzy linear equations. Description: PP: 33-45
